| Habitat use and diet of two sympatric felids - the Fishing cat (_Prionailurus viverrinus_) and the Jungle cat (_Felis chaus_) - in a human-dominated landscape in suburban Kolkata | |
| 2014 Full Book | |
This study examined habitat use and diet as a function of land covering two sympatric felids, the Fishing Cat (_Prionailurus viverrinus_) and Jungle Cat (_Felis chaus_), in a human dominated landscape in suburban Kolkata. The specific objectives were to (a) test whether land use types influenced the occupancy and intensity of habitat use at a finer spatial scale of the two species differently; (b) test whether their co-occurrence influenced their diet composition, in the light of reported competition between them; and (c) to discuss the implications of the findings on conservation of these to felids in the human-dominated landscapes. The study was conducted from January 2014 to June 2014. The study site of 1467 sq.km was divided into grids of 3 km ž 3 km. Scats were collected from 47 grids by searching trails where scats were likely to be found. Predator identity was assigned to scats through amplification and sequencing of a portion of the 16srRNA region of mitochondrial DNA. The prey remnants in the scats were separated broadly into major taxa. Further, rodents were identified to species level using dentition on the lower jaw obtained from scats. I digitized Google Earth imagery to map different land cover types, at a scale of 1.5 km ž 1.5 km, giving a total of 188 sub-grids from 47 grids. I modelled occupancy as function of the area under different land cover types, using data from a larger spatial scale of grids of 3 km ž 3 km. I modelled the number of scats in sub-grids, an indicator of intensity of habitat use, as a zero-inflated regression function of different land cover types. |
